Background:

Promoting functional activation of the central sensorimotor system is crucial for neurorehabilitation.
Non-invasive brain imaging techniques are vital for monitoring and guiding rehabilitation interventions.

Purpose of the Study:

To validate an adaptive closed-loop visuomotor task for facilitating cortical excitability.
To assess the impact of adaptive task difficulty on sensorimotor system activation.

Main Methods:

Developed a novel visuomotor task with adaptive difficulty based on real-time sensorimotor activation.
Measured brain activity using functional near-infrared spectroscopy (fNIRS).
Compared adaptive task group with a control group performing a task with random difficulties.

Main Results:

The adaptive group exhibited significantly increased bilateral sensorimotor cortex activation.
Enhanced effective connectivity was observed between prefrontal and sensorimotor areas in the adaptive group.
fNIRS confirmed differential brain activation patterns between groups.

Conclusions:

The fNIRS-based adaptive visuomotor task effectively facilitates neural activity in sensorimotor areas.
This task demonstrates high ecological validity and potential for improving hand motor function.
Adaptive neurofeedback tasks represent a promising avenue for neurorehabilitation strategies.
